 An issue must always correspond to a specific action with a well-defined completion state: fixing a bug, adding a new feature, updating documentation, or cleaning up code. Open-ended issues where the end result is not immediately clear ("come up with a way of doing translations" or "Add more features to rich text fields.") are better suited to [GitHub discussions](https://github.com/wagtail/wagtail/discussions), so that there can be feedback on clear way to progress the issue and identify when it has been completed through separate issues created from the discussion.

 As soon as a ticket is opened - ideally within one day - a member of the core team will give it an initial classification, by either closing it due to it being invalid or updating it with the relevant labels. When a bug is opened, it will automatically be assigned the [`type:Bug`](https://github.com/wagtail/wagtail/labels/type%3ABug) and [`status:Unconfirmed`](https://github.com/wagtail/wagtail/labels/status%3AUnconfirmed) labels, once confirmed the bug can have the unconfirmed status removed. A member of the team will potentially also add a release milestone to help guide the priority of this issue. Anyone is invited to help Wagtail with reproducing `status:Unconfirmed` bugs and commenting if it is a valid bug or not with additional steps to reproduce if needed.
